Destroy the World
Enough Weapons of Mass Destruction have been found on the Earth to destroy dozens of planets! Your objective is to obliterate the tyrannical human empire before they destroy the peace and freedom of the whole galaxy. To achieve this objective, you must stay alive against their attack and shoot all those elements on the earth with your laser cannon. Use your ARROW KEYS to control your UFO and press SPACEBAR to fire laser beams. Here are some tips for you: Homing rockets move faster than they accelerate - change directions quickly to avoid them, or to get them to slam into the ground (which can kill enemies, too). Rockets can be shot down but it's often not easy. Rockets detonate harmlessly when they run out of fuel, which take 4 seconds. Use the tilt of your ship to your advantage when firing lasers. Have fun!
